Investigation on the Adsorption and Photooxidation of Glycerol at TiO₂ Nanotubular Arrays

Figure 5

(a) Effect of G adsorption on the Nyquist plots; each curve is obtained after the sample was maintained in contact with (G)=0.1 M alkaline solution for increasing intervals of time 𝑡. Black symbols refer to test performed in the solvent without G. (b) Effect of G desorption. Solid lines refer to the model fit.
